NETE@ STATES Param' ori-ica EUGENE WHINNEN, 0F LOS ANGELES, CALIFORNIA, ASSIGNOR TO SULLIVAN MA- CHINE-RY COMPANY, A CORPORATION 0F MASSACHUSETTS CORE DRILL Application med December 26, 1923. Serial No. 682,599.

My invention relates to core drills.

It has for its object to provide an improved core barrel and more particularly an improved core barrel especially adapted to use in connection with oil Wells wherein mud iuid is used, this core barrel being of improved construction and providing improved means for supplying such mud fluid to the bottom of the hole.

In the accompanying drawings I have shown for purposes of illustration one form which my invention may assume in practice.

In these draivings,

Fig. 1 is a side elevation partially 1n section of one form of my improvement.

Fig. 2 is a sectional View on line 2-2 of Fig. 1.

Fig. 3 is a sectional vievsT on line 3-3 of Fig. 1.

Fig. 4 is a sectional view on line 4-4 of Fig. 1.

In this illustrative construction I have shown a core barrel comprising a main barrel member 1 of one diameter and a lower bit carrying section generally designated 2 of the same diameter, both sections of the same being improved as hereinafter described.

In my improved construction the member 1 is provided at its upper end with a coupling 3 of the threaded type having a iuid inlet -l extending partially therethrough, one end of the coupling being adapted to be c onnected to the rod line and the other being i threaded into the open upper end of the member 1. As shown, this member 3 .is also provided with a plurality of lateral fluid'passages 5, herein three, leading from the inlet It to the exterior of the coupling member, and these lateral fluid passages are connected through suitable pipe connections 6 Welded to the exterior of the member 1 as shown in Fig. 3 so that the fluid received throughxthe passage 4 in the coupling may be transmitted down along the outside of the barrel member 1. More particularly it Will be noted that the inner threaded end of the coupling 3 is in the form of a solid plug 7 so that thebore is plugged in such manner that all the liquid will pass through the pipes 6 While the core may rise up to the plug Within the member l as usual. Operatively connected to the bottom of the member fl is also a member 8 having an externally threaded reduced sleeve 9 threaded to the inside of the lower end of the member 1. This member 8 .is in turn provided with vertically disposed openings 10 therein which are formed in three radially disposed Wings 11 thereon and adapted to receive the lower ends of the pipes 6. VDuring assembly of the barrel after the members `1 and 8 are connected together the lower ends of the pipes 6 are inserted within the'bores 10 and thereafter the pipes are connected to the head 3 and suitably Welded in position. As shown, these openings 10 communicate with passages in a bit and core lifter carrying membei-.l which is threaded on to a reduced externally threaded sleeve 14 on the lower end of the member 8. Herein, both the member 8 and the member 13 are of the same cross section, i. e. that shown in Fig. 2, and slanting passages 15 are provided in the wings 11 on` the member 13 leading over to one edge of each wing so that the passage opens out into the bottom of the hole at one side` of the diamonds (not shown) which are carried on the lower ends of the Wings and on the lower endof the body of the member 13. As shown, a suitable core lifter 16, preferably of usual split or resilient form, is also carried within the member 13, preferably just below the threaded sleeve on the member 8.

As a result of my improved construction it will be noted that a large core is obtained from a relatively small hole and that at the same time it is made possible to supply fluid to the Wings from the core barrel and also to direct that lui'dto the bit through the wings thereof to the bottom of the hole Without passing any Huid around the core to the hole, this being a feature especially desirable Where the core is of a character not calculated to withstand the action of fluid. Moreover, it will be noted that this result is obtained at the same time that it is made possible to retain the Wing form of bit or bit and barrel for the eilect of the same in slapping the mud fluid into the hole as Well as to enable the Epl-dow of mud luid trom the bottom oi' the lVhile l have in this application specitically described one form which my invention may assume in practice, it will be understood that this form of the same is shown for purposes of illustration and that the invention `may be modiiied and embodied in various other forms Without departing from its spirit or the scope of the appended claims.
